death

(1) The cessation of all life functions in a living being, causing its life essence (also known as consciousness, spirit, or soul) to depart the physical body. Certain life essences have temporarily continued to exist in known realities after death clad in the astral body. An astral body whose physical form has died is called a ghost. The final fate of the life essence or soul after death is not known to science.

death gods

Superhuman beings who generally dwell on extradimensional worlds and who have at least temporary control of certain ghosts. These beings are sometimes physical and sometimes ectoplasmic. Such beings include Hela, Pluto, and Mephisto.

deity

A being perceived by some to be a god.

demon

dimension

A universe or realm containing space, matter, and energy which is separated from our own universe by some physical difference in the space, matter, and energy itself.

dimensional travel

The process of leaving the space of our universe and entering that of another one, accomplished by physical, psionic, or magical means. The mechanics of dimension travel are known to all but a few.

divergence

The process by which a single reality becomes more than one upon reaching a certain point in time. At this point of divergence, an event occurs differently in each diverging reality, leading to a radically different chain of events in each one.

divergent Earth

A world resembling Earth in every way up until a single juncture in time where events occurred a different way than they did on our Earth. There is an infinite number of possible divergent Earths, but no one knows how many actual divergent Earths there are. Divergent Earths exist in the equivalent space to our Earth's in other dimensions. A divergent Earth is an alternate Earth, but not a parallel Earth.

Doorway Between Worlds

A mystical portal in the Himalayas that opens onto other worlds.

Dyson Sphere

First theorised by physicist Freeman Dyson in the early 20th century, a race could take all of the mass of an entire solar system's planets and pulverize it into a thin layer of earth and atmosphere. This layer could be shaped into a sphere around the system's sun at a distance of one AU (astronomical unit - one Earth-Sun distance), creating an Earth-like habitat with over a billion times the surface area of Earth. The New Mutants encountered a Dyson Sphere when they were transported there by Lila Cheney, who uses it as a base of operations.
